Using SSH to connect to your Raspberry Pi
Earlier, when writing the SD card, we enabled SSH. This is a secure remote shell that lets us send instructions and files to and from the Raspberry Pi without having physical access to it.Windows, Linux, and macOS computers all have a terminal ssh tool to access remote SSH systems, like this Raspberry Pi. Let’s connect to the Raspberry Pi with SSH.
